Ink tank and printer

Abstract

An ink tank includes: a reservoir that stores ink; a supply port that supplies ink stored in the reservoir to a printer; a supply port sealing member that seals the supply port; an air port that communicates between an inside of the reservoir and an atmospheric space above an upper side of a liquid surface of the ink; and an air port sealing member which a needle tube is capable of inserting and pulling out of, and which seals the air port in a state where the needle tube is not inserted.

What is claimed is: 
     
       1. An ink tank which is accommodated in an accommodation section of a printer, the ink tank comprising:
 a reservoir that stores ink; 
 a supply port formed in the reservoir that supplies ink stored in the reservoir to a printer; 
 a supply port sealing member that seals the supply port; 
 an air port formed in the reservoir that communicates between an inside of the reservoir and an atmospheric space above an upper side of a liquid surface of the ink; and 
 an air port sealing member which seals the air port outside the accommodating section, 
 wherein the air port sealing member permits an air communication between an inside of the reservoir and an atmospheric space by an atmosphere passage formed in a lid section of the accommodation section. 
 
     
     
       2. The ink tank according to  claim 1 , wherein the air port sealing member is formed of an elastic material. 
     
     
       3. The ink tank according to  claim 1 , wherein the atmosphere passage has a plurality of bending sections. 
     
     
       4. A printer comprising:
 a receiving section of an accommodating section that receives supply of ink from a supply port of an ink tank; 
 the accommodating section that accommodates the ink tank; 
 an atmosphere passage that is formed in a lid section of the accommodating section and which introduces atmosphere into the ink tank through an air port formed in the ink tank. 
 
     
     
       5. The printer according to  claim 4 , wherein the atmosphere passage has a plurality of bending sections. 
     
     
       6. The printer according to  claim 4 , wherein the lid is provided to be pivotable by being connected to the accommodating section. 
     
     
       7. The printer according to  claim 4 , wherein the accommodating section accommodates a plurality of ink tanks in a row in a first direction, and
 wherein the lid has a pivot shaft of which an axial direction is the first direction and a needle tube is provided on the pivot shaft side from a center position of the lid in a direction intersecting the first direction. 
 
     
     
       8. The printer according to  claim 4 , wherein the accommodating section accommodates the plurality of ink tanks in a row in the first direction, and
 wherein the lid has a pivot shaft of which the axial direction is a direction intersecting the first direction and an ink tank in which monochrome ink is accommodated is disposed in a position closest to the pivot shaft. 
 
     
     
       9. The printer according to  claim 4 , wherein the accommodating section accommodates a plurality of ink tanks, and
 wherein the atmosphere passage is separately provided for each ink tank. 
 
     
     
       10. The printer according to  claim 4 , wherein the accommodating section accommodates a plurality of ink tanks, and
 wherein the lid is separately provided for the ink tank.
